Ingredients
1unbaked 9-inch pie crusthomemade or store-bought
3cupsfresh rhubarbchopped
3large eggs
1 ½cupsgranulated sugar
¼teaspoonsalt
¼cupall-purpose flour
1teaspoonvanilla extract
1cupwhole milkor half-and-half for richer custard
2tablespoonsunsalted buttermelted
Instructions
Preheat the oven to 375°F (190°C). Place your pie crust into a 9-inch pie pan and crimp the edges. Set aside.
Prepare the rhubarb by washing and chopping it into ½-inch pieces. Spread it evenly into the bottom of the unbaked crust.
Make the custard filling: In a mixing bowl, whisk together the eggs, sugar, flour, salt, and vanilla extract. Slowly whisk in the milk until fully combined, then stir in the melted butter.
Pour the custard mixture gently over the rhubarb in the pie shell. Tap the pan lightly on the counter to remove air bubbles.
Bake for 50–55 minutes, or until the custard is set and the top is lightly golden. A knife inserted near the center should come out clean.
Cool the pie on a wire rack. It will continue to firm up as it cools. Serve slightly warm or chilled.
Notes
Use fresh rhubarb: Crisp, bright red stalks offer the best flavor and texture.
Prevent soggy crust: Bake the pie on a preheated baking sheet to help the bottom crisp up.
Cool completely before slicing: This ensures clean, firm slices and better texture.
Don’t overbake: Remove from the oven when the center still has a slight jiggle; it will set as it cools.
